The star-shaped axes, right of centre, are a result of shrinkage during decay and desiccation of the stems (scale bar = 1mm).   Introduction One of the first Rhynie chert plants to be described and perhaps the most abundant is the form Rhynia . The plant was originally described and classified by Kidston and Lang in 1917 , 1920a and assigned the species name Rhynia gwynne-vaughanii . Another plant now known as Aglaophyton , possessing a slightly similar anatomy, was originally described by Kidston and Lang in their 1917 paper as also belonging to Rhynia gwynne-vaughanii , but differs significantly in its vascular anatomy and was subsequently reassigned (see also Aglaophyton ). Unequivocal gametophytes of Rhynia have recently been discovered ( Kerp et al . in press ) and will be illustrated here once published. The overall

my first blog

Basically in +3 level or in graduation level biological students come across various fundamental topics  on biology.It's my first blog and I'm going to publish some posts on this blog about some biological topic. I will describe about the pteridophytes in my next blog and please stay connected with me.                                                                                                                                                    THANK YOU
